Skin lesions caused by Erysipelothrix rhusiopathiae in an aborted swine-fetus

摘要

Erysipelothrix rhusiopathiae infection has a worldwide distribution and may be characterized by skin lesions, vegetative endocarditis, arthritis and reproductive problems such as abortion, increased stillbirths and smaller litter size. This report associates an aborted swine fetus with Erysipelothrix rhusiopathiae infection. The main gross lesions observed in an aborted swine fetus (Large White) were well circumscribed whitish areas in the skin of the periocular region, face, neck, scapula, and hindquarter. Microscopicaly, these lesions were characterized by mild mononuclear perivasculitis associated with gram-positive rods. Aerobic cultivation from samples of lungs, liver, stomach content and skin revealed pure cultures of Erysipelothrix rhusiopathiae.
